To all whom 'it may concern:

Beit known that I, WILLIAM LINHOFF, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have 4invented a new and useful Fender for Lawn-Sprinklers, of which the following is a specification.

The invention relates to a fender for lawn sprinklers.

The object of the present invention is toprovide a simple, inexpensive and eHicient device, designed to be readily applied to various forms of' lawn s rinklers and sprayers, and adapted. to cut or@ the spray at one side of a sprinkler or sprayer to a greater or less degree, adjacent to side walks and analogous places, to prevent the water from discharg- Jng over, wetting and wasting on such surfaces. j

A further object provide a fender of to enable sprinklers of the invention `is to this character, adapted to be advantageously employed for spraying narrow strips of arking, gardens and the like, and capab e of adjustment to confine the spray'within the desired limit.

Another object of the invention is to provide means for adjustably mounting the fender on a sprinkler, and of enabling the former to be properly positioned with relation to the latter to secure the. best results.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various C anges in the form, proportion, size-and minor details of construction, within the Sco e of the claims, maybe resorted to witiiout de arting from the spirit or sacri' icing any o the advantages of the invention.

In the drawing z-F igure 1 is a perspective view of a fender, constructed in accordance wn yap lied to a ongitudinalpsectio'nal View of the same. Fig. 3 is a plan view, showing the fender applied to a sprinkler having integral supporting arms for holding; .the fender. Fig. 4 1s a detail view, illustrat' lng the arrangement of the shoulders of the arms for supporting the frame of the fender.

sprinkler. Fig. 2 is a l which Like numerals of reference designate cor- .responding parts in all the figures of the drawing.

1 1 designate a pair of similar blades or win s, spaced apart to permit water to be i disc arged between them, and hinged to a substantially oblong frame or support 2, and ada ted to be adjusted independently of eacli) other and to be raised or lowered to cut off a portion of the spray of a sprinkler 3, or to confine such spray within the desired limits. The oblong frame, which isvcomposed of two sides and connecting ends, has its side portions bowed outwardly at the center at 4 to project such bowed or outwardly curved portions 4 beyond the hinged edges of the blades or wings to facilitate the attachment of the frame 2 to a clamp 5,

is adapted to detachably-secure the fender to the sprinkler. The oppositely bowed portions 4, form a substantially circular central ortion and provide, at the center of the iiiame, an enlarged open portion, through which the water from the sprinkler is' discharged. The end portions 6 of the frame 2 are extended beyond the ends of the sides or wings, and are bowed slightly to enable them to be engaged by the clamp 5, which is adapted to be connected to either side orend of the frame and which adjustably receives the same, whereby the device is susceptible of attachment to a large variety of sprinklers and sprayers.

The blades or wings, which are constructed of sheet metal, or other` suitable material, may be rectangular, or any other preferred shape, and they are provided at their lower edges with hinge elements 7, having eyes 8 to receive the sides of the frame 2 at the terminals of the central bowed portions 4, whereby the sides or wings are hinged to the frame. The frame is constructed of round wire, or other suitable material, and it provides pintles or pivot portions, on which the blades or wings swing. The hinge elements 7, which may be formed by doubling plates or pieces of sheet metal, or other material, are provided with integral springs 9, bowed or corrugated longitudinally to stiffen them ,l and having projecting portions, which fricj tionally engage the sides of the frame 2, whereby the blades or wings are secured in their adjustment. The hinged wings or l curved portion 17 is provided at its opposite members 1 are adapted to be readily swung upwardly and downwardly, and the springs operate automatically to hold the Said wings or members against accidental movement, and they have sufficient power to withstand the force of the spray. The springs 9 are substantially semicylindrical, and the frame is engaged by the side edges of the springs.

The sprinkler 3, which has a substantially cylindrical head or nozzle, is provided at the top with a discharge opening, and the blades or wings, which are supported above the head or nozzle at opposite sides of the discharge opening, are independently adjustable and either or both may be raised, and when one is raised and the other lowered to a horizontal position, the spray'will be cut off at one side. This will enable the sprinkler to be arranged close to a walk, or similar place, without wasting the water on the same. When both of the blades or wings are swung upward, the spray will be constricted or cut oil' at opposite sides and may be confined within the desired limits. This will enable` narrow strips of parking, and similar places to be advantageously sprayed, without wasting the wateren the adjacent paved portions of a street, or the like. The blades or wings are also adapted to be arranged in substantial parallelism and at an inclination, as illustrated in Fig. 2 of the drawing, for throwing thespray in any desired direction, and they may be converged to operate in the nature of a nozzle.

The clamp is composed of an upper plate or member 10 and a lower member 11, constructed of stout spring wire, or other resilient material, which is adjustably connected with the upper plate or member by means of a bolt 12 and a winged nut 13. The upper plate or member is provided with a jaw 14, which extends downwardly and forwardly at an inclination to coperate with a correspondingly shaped jaw 15 of the other member 11 in clamping the frame 2, as clearly illustrated in Figs. 1 and 2 of the drawing. The member 11 is composed of two sides and a connecting transverse portion 16, and the engaging portions of the jaws are oppositely curved to present c'oncave faces to the frame 2, and to enable the latter to be securely confined in the clamp. The clamp also forms a hinged connection for the frame to enable the latter to be swung upwardly and downwardly, to osition it properly with relation to the sprin er. The inclination of the jaws afford an adjustment for the fender, and enables the same to be raised and lowered by arranging it at different points along the inclined jaws.

The rear end of the plate or upper member 10 is curved downward between the sides of the other member 11, and the downwardly edgeswith notches 18 to receive the sides oi' the lower member 11, whereby the upper plate or member is ulcrumed on the lower member, and it is adapted to operate in the nature of a lever for clamping the frame 2.

The sides of the lower member 11 are retained in the notches 18 of.the upper plate or member by means of a transversely disposed connecting plate 19, extending across the member 11 in advance of the downwardly curved portion 17 and having upturned inwardly curved ends 20, which partially embrace the sides of the member 11, as clearly shown in Fig. 1 of the drawing. The transversely 'dis osed connecting plate or member is provi ed with a central perforation for the reception of the bolt 12, which has a head at its lower end to engage the plate 19, and the u per threaded portion of the bolt is engaged y the nut 13, which bears against the upper face of the plate or member 10. By tightening the nut, the frame 2 may be tightly clamped between the jaws 14 and 15.

The inner or rear end portionsof the sides of the-lower member 11 of the clamp are coiled to form circular clamping loops 21, which are resilient, the resiliency being increased by leaving the terminals of the wires free. The clamping loops are adapted to engage the opposite sides of a hose 22, -r other tubular connection with the sprayer, and it will support the fender in the desired position above the discharge opening of the Sprinkler. The resilient clamping loops are adapted to engage the hose 22 at any desired point, and the clamp enables the fender to e moved backwardly ,or forwardly, and it also permits the fender to be instantly attached to and removed from the sprinkler.

The clamp will enable the fender to be applied to various forms of sprinklers and sprayers, but the frame 2 may also be directly applied to a sprayer or sprinkler 23, without the aid of the clamp. VThe sprayer 23 is provided at opposite sides with upwardly extending arms 24, having reduced terminals to receive the ends of the frame, which is supported upon the shoulders 25, formed by reducing the ends of the arms 24. The curvmg and bowing of the frame 2 renders it suliciently resilient to rictionally engage, and thereby positively clamp, the arms 24, so that the fender will be securely retained on the sprinkler 23.
